i have 2 JBL 2226H in parallel and a JBL 2450J loading a JBL 2360.

Is it possible to drive this combination as a two-way or is it better to use a HF-driver like the JHL 2405?
Is for a two-way the SL-diaphragm better?
Is it possible to compensate the HF-roll-off of the 2450/2360 combo?

If yes, can you send me a schematic of the crossover?

Thank you for the answers.

Dieter
